The calm after the storm? There is still the sense of uncertainty in the air though. #berklee #boston

The Boston Athletic Association (B.A.A.) extends its deepest sympathies to all those who were affected by Monday's tragic events. Those who lost their lives and were injured are in our thoughts and prayers.

It is a sad day for the City of Boston, for the running community, and for all those who were here to enjoy the 117th running of the Boston Marathon. What was intended to be a day of joy and celebration quickly became a day in which running a marathon was of little importance.

We want to express our deepest gratitude to all of the B.A.A. medical personnel and volunteers and the City of Boston’s first responders who reacted so courageously to help save lives. Special thanks to the loyal Boston Marathon community – over 8500 volunteers, 1000 medical personnel, the organizing committee, and hundreds of thousands along the race route – who make the experience what it is for all our runners, who are hurting today.

We would like to thank the countless people from around the world who have reached out to support us over the last 24 hours.

We are cooperating with the City of Boston, the Commonwealth of Massachusetts, and all federal law enforcement officials in the investigation and the effort to bring those responsible for this tragedy to justice, so we are limited in what information we can provide.

Boston is strong. Boston is resilient. Boston is our home. And Boston has made us enormously proud in the past 24 hours. The Boston Marathon is a deeply held tradition – an integral part of the fabric and history of our community. We are committed to continuing that tradition with the running of the 118th Boston Marathon in 2014.

RT @RedCross: Thanks to generosity of volunteer blood donors there is currently enough blood on the shelves to meet demand. #BostonMarathon
